To create a sterile field, follow these steps: 1. Perform hand hygiene: Use an alcohol-based hand sanitizer or wash hands with soap and water. 2. Assemble supplies: Gather all necessary sterile equipment and supplies. 3. Prepare the patient: Clean the patient's skin with an antiseptic solution. 4. Don sterile gloves: Ensure hands do not touch anything non-sterile. 5. Drape the area: Use sterile drapes to cover the patient's body, leaving only the operative site exposed.
